Executive Summary

This vulnerability involves improper handling of insufficient entropy in AMD CPUs, which could allow a local attacker to influence the values returned by the RDSEED instruction. This means the random values generated may not be sufficiently random.

Impact Analysis

The impact of this vulnerability is that an attacker with local access could manipulate the random values generated by the RDSEED instruction, potentially compromising cryptographic operations or security mechanisms that rely on high-quality randomness.
